Application filed March 11, 1915. Serial No. 13,786.

To all whom it may concern Be it known that we, BERNARD TEWELOW andSoLoMoN TnwELow, citizens of the United States, residing at Baltimore,in the State of Maryland, have invented certain new and usefulImprovements in Cutters for Removing Hair from Cavities, of which thefollowing is a specification.

This invention relates to a safety cutter for the removal of short hairsthat grow in the human nostrils and ears.

One object of the invention is to provide a safety cutter that ismounted on a shank or handle to be revolved and which cutter will removehairs in the nostril or in an ear by inserting the cutter in positionclose to the hair and then revolving the shank and cutter.

The invention is illustrated in the accompanying drawing in which,-

Figure 1, shows the manner of using the cutter in removing a hair fromthe nostril.-

Fig. 2, is a side view of the cutter.

Fig. 3, is a longitudinal section of the cutter. i

Figs. 4 and 5, are views of the cutterblade.

Fig. 6, is a face view of the back plate of the holder for thecutter-blade.

Fig. 7, is the safety guardfor the cutterblade. Y

Fig- 8, is a cross-section on the line 88 of Fig. 2, showing theposition of the back plate, cutter-blade and guard.

Fig. 9, is a cross-section on the line 9-9, of the back-plate. V

Fig. 10, is a cross-section on the line 1010 of Fig. 7, showing thescrew shankof the guard.

Referring to the drawing the cutter device as a whole comprises a shankor handle 11, which preferably has polygonal sides and at one end has asocket 12, that opens axially and which is internally screw-threaded.The three parts of the cutter proper consist, of a cutter blade 13, aback plate holder 14, and a safety guard 15,the said cutter-blade beingbetween the back plate and guard,and each of said three parts having ashank and all the shanks in alinement, a screw thread 16, around theexterior of the two outer'shanks enters the screwthreaded socket-.12, inthe end of the handle, and thereby said socket binds together the threeparts of the cutter proper.

' The cutter-blade 13, shown separately in right angle on its concaveface and covers the end 24, of the cutter-blade when the parts areassembled. This back plate 14:, has a reduced end or shank 25, that isconcave on its front and rounded on its exterior,

.and the exterior has the screw-thread 16,

already mentioned.

The guard plate 15, shown separately in Figs. 7 and 10, has a partlyrounded surface that takes against the thin cutter-blade 13, and isprovided with two pin-holes 26, with which the pins 23,.of the backplate 14, engage"; this guard plate has a shank-end 27, shown in Fig. 7,and in cross-section in Fig.

' 10; the exterior rounded part of this shank is screw-threaded as at16.

When the three parts of the cutter proper are assembled the cutter endin cross-section is more than half cylindric, and the thin cutter-blade13, is between the back plate 14, and theguard plate 15, as seen in Fig.8, and the pins 23, that are fixed on the back plate extend through theholes 19, in the blade, and engage with the holes 26, in the guard asseen in Fig. 2. All, three of the shanks, 17, 25 and 27, are inalinement together and these three enter the socket 12, in the handleand the screw-thread 16, on the two, outer shanks engage thescrewthreadof the socket and thereby the several parts are kept in their properrelative position.

The manner of using this hair-cutting tool to remove a hair from thenostril is shown in Fig. 1. By placing the end of the cutter into thenostril and by the action of the human thumb and fingers revolving thehandle 11 back and forward, a hair may be readily out instead of beingextracted root and all,as the latter is often productive of sores. Inlike manner hairs may be removed from the ear.

Having thus described our invention what we claim is, y

In a safety cutter for removing hair from til the cavity of the humannostrils and ears the combination with a handle having a threaded socketin one end, of a back plate holder having a concave inner side and aconvex outer side and provided at one end with a shank which latter hasa concave inner side and a threaded convex outer side; a guard alsohaving a concave inner side and a convex outer side and provided with ashank which projects from one end thereof which latter shank has aconvex innerside and a threaded convex outer side and a normally flatspring blade between the back Y plate holder and the guard, and saidblade also having a flexible shank at one end which projects between theinner concave side of the plate holder and the inner convex side of theguardand said three shanks projecting into and the threads on the plateholder shank and the guard shank engaging the threads in thehandle-socket and clamping the shank of the blade between them.

In testimony whereof we aflix our signa tures in presence of-twowitnesses.
